AUXILIARY-AIR-,INLET SHUT-OFF VALVE.

Application filed .April 7, 1919, Serial No. 288,194. Renewed January 30, 1922. Serial No. 532,899.

To all whom t may concern.'

Be it known that we, CHARLES A. RIVERS and FRANCIS B. STUART, both citizens of the United States, and residents of El Paso, in the county of El Paso and State of Texas, have invented certain new and useful Tmprovements in an AuXiliary-Air-Inlet Shut- Off Valve, of which the following isa specification.

This invention relates to an improved shut-ofi valve forthe auxiliary air inlet of an internal combustion engine, and. more particularly to certain improvements in a device of the character disclosed in the pending application for patent of Charles A.

Rivers, Serial No. 253,841, filed September 12th, 191e.

The present .invention has for one of its objects to provide av simple and effective auxiliary air inlet valve adapted to be operated from the dash board of a vehicle either by means of a hand actuated rod or a foot pedal to close the open end of the air inlet.

It is also a further general object of our invention to provide an auxiliary air inlet shut-off valve which may be easily and quickly actuated when the engine is running and the throttle closed to cut off the inlet of auxiliary air to the manifold, and which may be easily and quickly applied in its operative position and is not liable to get out of order.

Having the aforementioned objects in view, the present invention comprehends certain novel and improved combinations of mechanical elements, and the structural characteristics thereof, as will be more fully developed in the following description and subsequently incorporated in the subjoined claims. .c

Figure 1 is a side elevation showing our improved shut-on' valve; y

Figure 2 iS a top plan view showing the valve in closed position; and

Figure 3 is a sectional view of the end of an air inlet pipe, the standard upon .which it is mounted, and the. valve pivotally mounted on said standard.

Referrin in detail to the drawings, 5 designates t e auxiliary air vinlet pipe which,

at onevof its ends, is tapped into the trunkwall ofthe engine manifold. The other end of this pipe is mounted upon a suitable support indicated at 6, the latter end of the pipe being open to the atmosphere.

- Tn either case,

As herein illustrated, we have shown a rod 13 loosely connected at one of its ends to the upper end of the valve arm 11. This rod extends through a sleeve or other suitable guide means which may be secured in the vehicle dash board Tt will be seen from an examination of Figures l and 2 of the drawings that when the valve member is disposed in an intermediate position, the end of the air inlet pipe 5 is open between the diverging wings 12. The operator mayl close the inlet-pipe and shut 0H any communication between the open end thereof and the atmosphere by either pushing or pulling upon the rod 13. Tf this rod is pulled, the wing 12 on the left will be `moved over the open end of the pipe 5, whereas if the rod is pushed through the dash board, the righthand wing 12 will be thus moved over the open end of the pipe. the admission of auxiliary air to the manifold is completely cut off.

From the foregoing description, taken in connection with the accompanying drawings, the construction, method of operation and several advantages of our improved shut-ofi' valve will be clearly and fully understood. As the valve is wholly disposed exteriorly of the air inlet pipe, it will operate very freely, as its action is not liable to be impeded by foreign matter suchvas might possibly occur if the valve were mounted within the inlet pipe. It will also be seen that the valye member can be easily and quickly applied to the end of the pipe in its operative position or removed therefrom. We have herein shown one means for applying the valve member and pivotally supporting the same, but it is manifest that numerous other ways of mounting this valve be constructed in various sizes and owing vto the fact that the valve member in its entirety, may be stamped or cut from a will be appreciated that single metal plate, it

produced at relatively the device can be small cost.

The preceding description and the accompanying drawings disclose one practical embodiment of the invention, which, however, may likewise be exemplified in numerous alternative constructions. Accordingly the invention as herein claimed is to be considered as inclusive ot' all legitimate equivalents for the various elements employed as well as other contemplated arrangements thereof, which may satisfactorily accomplish the desired results.

In some makes ot vehicles, it may be more convenient to apply the device on the opposite side of the engine from the arrangement illustrated in the drawing. This can be readily done in view of the fact that the valve element is provided with the two diverging wings 12, the valve being operated in the same manner and with the same motion of the operating rod in either case.

l. The combination with an auxiliary air inlet for internal combustion' engines connected to the engine manifold and in communication with the atmosphere at one of its ends, a valve plate placed externally of said air inlet and being arranged to move transversely across the open end thereof whereby to control the entranceof atmospheric air, said valve plate being pivoted in anintermediate position whereby it may be moved in either direction to close the inlet port.

2. The combination with an auxiliary air inlet pipe for internal combustion engines connected at one of its ends to the engine manifold and in communication at its other end with the atmosphere, and a valve plate placed externally of the pipe and being mounted to move transversely with respect to such pipe whereby to open and close the end thereof in communication with the atmosphere, said plate being so constructed as to close the port when moved in opposite directions.

3. In combination with the intake manifold of an internal combustion engine, and an auxiliary air inlet pipe connected thereto and having one of its ends normally in communication `with the atmosphere,

transversely across said pipe in either of two opposite directions and so constructed and mounted as to close communication with the atmosphere through atmosphere,

of a valve such pipe but to open the communication through the pipe when the valve plate is in an intermediate position, and means for shifting said valve plate.

4. rli`he combination with an auxiliary air inlet pipe for internal Combustion engines connected at one of its ends to the engine manifold and in communication at its other end with the atmosphere, and a valve member pivotally mounted upon the latter end of the, inlet pipe and having spaced parts operable upon a movement 4of the valve member in reverse directions from an intermediate position to close the end of the inlet pipe and shut olf communication with the atmosphere.

5. The combination with an auxiliary air inlet for internal combustion engines having an open end in communication with 'the atmosphere, of a valve member mounted for movement in either one of two directions to close the open end of the air inlet, said valve being exterior of the pipe and movable transversely across the open end thereof, and means for manually operating said valve member.

6. The combination with an auxiliary air inlet for internal combustion engines having an open end in communication with the of a valve member mounted exteriorly of the inlet and .movable transversely across the open end of the air inlet in either one of two directions to close the same, said inlet being open for the admission of air when the valve member is in an intermediate position. and longitudinallymovable means for manually operating said valve member.

7. The combination with an auxiliary air inlet pipe for internal combustion engines having an open end in communication with the atmosphere, of a valve member pivotally mounted upon said pipe and having diverging shut-off wings movable transversely across the open end of the air inlet pipe to close the same, and manually operable means connected to said member to move the same int either directiony and dispose one of said Wings in its closing position.

ln testimony that they claim the foregoing as their invention, they have signed their names hereunder.
